  • camera 106 may include tracking mechanisms that "lock onto" a particular object, such as the user, and may provide updated indications of the position of camera 106 to VCSCD 102.
  • WPVCD 104 may provide an indication of the position, for example with respect to a user, to VCSCD 102.
  • camera 106 may provide an indication of the position, for example with respect to a user, to VCSCD 102.
  • Camera 106 may wirelessly provide the indication of the position and specifications of camera 106 in response to a request for that information from VCSCD 102.
  • WPVCD 104 may receive a request to implement shooting of a video stream from VCSCD 102 (block 610). For example after VCSCD 102 selects camera 106 at block 514 of process 500 hereinabove, camera 106 may receive a request to implement video conference service (shooting the video of the user) and an Internet protocol (IP) address of a recipient second party 302.
  • IP Internet protocol
  • WPVCD 104 may implement the video conference service.
  • camera 106 may implement shooting, encoding, and streaming of the video stream to second party 302.
  • Camera 106 (and display 112) may include an extra layer in a camera driver for camera 106 that implements the video streaming to convey to third -party machine- readable instructions for video conferencing (e.g., a video chat program via which the users are video conferencing) that VCSCD 102 is implementing the video conference service (e.g., third party machine-readable instructions acts as if video shooting and streaming is being done by a default camera (e.g., an integrated camera) associated with VCSCD 102).
  • a default camera e.g., an integrated camera
  • Second party 302, and the third-party machine-readable instructions may then communicate with VCSCD 102 via the driver for camera 306 in a similar manner as if the communication was with a single device (i.e., functionally, from the perspective of third -party machine-readable instructions, camera functions and streaming implemented in camera 306 by VCSCD 102 appear to be from VCSCD 102).
  • logic that performs one or more functions.
  • This logic may include hardware, such as a processor, a microprocessor, an application specific integrated circuit, or a field programmable gate array, software, or a combination of hardware and software.

Abstract

L'invention concerne un procédé qui consiste à établir, par un dispositif de commande de session vidéo (102), une session de visioconférence. Le dispositif de commande de session vidéo (102) comprend au moins un composant de fourniture de service de visioconférence. Le procédé consiste à identifier une spécification du ou des composants de fourniture de service de visioconférence. Le procédé consiste également à identifier une position du ou des composants de fourniture de service de visioconférence. Une spécification d'au moins un dispositif de visioconférence périphérique sans fil (106, 112) est identifiée. Une position du ou des dispositifs de visioconférence périphériques sans fil (106, 112) est également identifiée. Le procédé consiste également à déterminer une combinaison de dispositifs pour fournir les services de visioconférence sur la base des spécifications et des positions relatives du ou des composants de fourniture de service de visioconférence et du ou des dispositifs de visioconférence périphériques sans fil (106, 112). Les services de visioconférence sont mis en oeuvre à l'aide de la combinaison déterminée de dispositifs.
